C3 Vs C4 Plants
C3 plants are said as cool season plants while C4 plants are said as warm season plants. C 4 plants are usually identified by their higher 13 C 12 C isotopic ratio compared to C 3 plants or their typical leaf anatomy.

Both C3 and C4 plants require 6 molecules of CO2 and 12 molecules of water to synthesis one molecule of glucose.
C3 vs c4 plants. They carry out a dark reaction. O2 can bind to Rubisco instead of CO2. C4 plants About 85 of total plants species are C3 and only 15 are C4 plants.
Furthermore they have chloroplasts to carry out photosynthesis. C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Everything being equal if you raise the CO2 levels the C3 plants will theoretically benefit from increased CO2 more than C4 plants Most of the crops grown on the Prairies including wheat barley canola flax and soybeans are C3 plants.
Examples of C4 plants include corn sorghum sugarcane millet and switchgrass. The carbohydrate product of both C3 and C4 cycle is a three-carbon sugar phosphate molecule known as Glyceraldehyde 3 phosphate G3P. C3 plants fix the carbon dioxide with the help of Rubisco through a process called photorespiration.
Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night. The main difference between C3 C4 and CAM photosynthesis is that C3 photosynthesis produces a three-carbon compound via the Calvin cycle and C4 photosynthesis produces an intermediate four-carbon compound which split into a three-carbon compound for the Calvin cycle whereas CAM photosynthesis gathers sunlight during the day and fix carbon dioxide at night. As a result in high light and temperature environments C4 plants tend to be more productive than C3 plants.
Surrounding the leaves are mesophyll cells that contain a much more active enzyme called phosphoenolpyruvate PEP carboxylase. C3 plants are photosynthetic plants whereas C4 are tropical plants. C4 plants examples are corn sorghum sugarcane millet and Panicum virgatum switchgrass.
C3 plants vs. While most are graminoids other growth forms such as forbs vines shrubs and even some trees and aquatic plants are also known among C 4 plants. Therefore the efficiency of photosynthesis in C4 plants is higher than its efficiency in C3 plants.
Also both types of plants carry out the same light reaction. C3 Plant and C4 Plants both are productive but C4 plants are more productive and efficient. Examples of C4 plants include corn sorghum sugarcane millet and switchgrass.
C4 photosynthesis is a biochemical modification of the C3 photosynthesis process in which the C3 style cycle only occurs in the interior cells within the leaf. However the C4 anatomical and biochemical adaptations require additional plant energy and resources than C3 photosynthesis and so in cooler environments C3 plants are. Both C3 and C4 plants fix carbon dioxide and produce carbohydrates.
C3 grasses release 833 molecules of water per co2 molecule while C4 grasses release 277 molecules of water. The main difference between C3 and C4 plants is that single fixation of carbon dioxide is observed in C3 plants and double fixation of carbon dioxide is observed in C4 plants. Both C3 and C4 plants.
C4 have higher water efficiency than C3 plants. Corn and sorghum are C4 plants which is why heat units are important to these crops. What are the Similarities Between C3 and C4 Plants.
